She also posted the same collage as Hyoyeon with the caption, “Goodbye now to the repetitive sadness in this world” (another lyric from “Into the New World”) and included “Congratulations” and “I love you” in the hashtags.

Taeyeon posted on their anniversary with a video of the group, complete with the addition of a photo of Yuri, who wasn’t in the original shot. “Perfect,” she wrote, and included four emojis of pairs of dancing women to represent the eight members.

YoonA uploaded a shot of the group from a recent SMTOWN concert and wrote, “My Girls’ Generation and my SONE who are so precious to me. Thank you for always being with me for the past ten years, I love you~ The precious people who always make me touched — let’s keep being happy in the future too!”
